2. Define variable labels and format VARIABLE LABEL -- A "Variable Label" is an alternate (and usually more explanatory) description of a variable. For example, a label for AGE might be "AGE in 1990," and for ID, "Identification Number." A Label makes the output more readable. VARIABLE FORMAT - A "Variable Format" is a series of labels describing categories. For example, for the variable ANSWER with values 0 and 1. Define 0=”No" and 1="Yes." When output is generated, No and Yes are used rather than the cryptic 0 and 1. texasoft.com2
